Bin Rewrite Progress!

My vision for the bin library is to provide great and consistant support for binary minipulation... The old version was not consistant with how I wanted things to work. Great things to come! Note: A lot breaks Progress: [==========90%======== -] All that is left is the virtual file system stuff! Everything else is all good! A lot of useless and unneeded functions have been removed while adding some more useful ones!

List of new methods

• bin.newFromBase64(data) -- returns a bin object from base64 data
• bin.newFromBase91(data) -- returns a bin object from base91 data
• bin.newFromHex(data) -- returns a bin object from hex data
• bin:read(n) -- works just like normal read on a file for both stream/bin files
• bin:sub(a,b) -- works like string.sub() but for bin objects
• bin:seekSet(n) -- sets the seek position on the file
• bin.toBase64(s) -- returns a base64 encoded string from the input string
• bin.fromBase64(s) -- converts the base64 data back into its original string
• bin.toBase91(s) -- returns a base91 encoded string from the input string
• bin.fromBase91(s) -- converts the base91 data back into its original string
• bin.getnumber(num,len,fmt,func) -- turns num into a binary string, len is what to fit it into, 4 bytes, 5+ bytes. fmt is either %e for little endian or %E for big endian defualts to %E
• New infinabits! Works like bits, but supports numbers up to infinity
• bin.registerBlock(t,funcG,funcA) -- allows you to add custom block commands, I implemented the table block command using this feature, look at extrablocks.lua in the bin folder
• binobj:getMD5Hash() -- returns the md5 hash of the bin file
• bin.getBitsInNum(x) -- returns the number of bits needed to store a number

List of converted methods and their status

• log(data,name,fmt) bin.getLuaVersion()
• bin.load(filename,s,r) -- loads a file into memory as a virtual file
• bin.new(data) -- Does not accept b64 or hex data anymore! Use new methods for that ^^^ -- creats a new virtual file
• bin.stream(file,lock) -- opens a file in updating mode. Works just like a binobj
• bin.newTempFile(data) -- creates a streamed file usine lua's io.tmpfile() so its removed when the program is done
• bin:getSize(fmt) -- gets the size of the string fmt is how you want to format it. left empte returns number of bites as a lua number supports lua formats! And also I added the %b format for base64
• binobj:getData(a,b,fmt) -- returns the data of the object as a string, supports %x(hex), %X(HEX) and %b(base64)
• bits.new(n) -- creats a bits objects. This library is all about numbers and manipulation at the bit level
• bin.newVFS() -- soon
• bin:tackE(data) -- tacks data onto the end of a file
• binobj:tofile(path) -- binobj to a file on the disk. Does not work with stream files! Might allow it to rename stream files at a future point
• bin.loadVFS(path) -- soon
• bin:newDataBuffer(size,fill) -- creates a buffer object. Buffers allow fast and easy byte manipulation bin.bufferToBin(b) bin.binToBuffer(b) bin:getDataBuffer(a,b) bin.newNamedBlock(indexSize) bin.newStreamedNamedBlock(indexSize,path) bin.loadNamedBlock(path) bin.namedBlockManager(arg)
• bin.randomName(n,ext) -- returns a random filesystem safe string, can add an extension to be created with it as well bin.NumtoHEX(n) bin.HEXtoBin(s) bin.HEXtoStr(s)
• bin.tohex(s) -- converts a string into hex
• bin.fromhex(s) -- takes hex data and turns it into a string
• bin.endianflop(data) -- swaps between big/little endian
• bin.getVersion() -- returns the libraries version as a string bin.escapeStr(str) bin.ToStr(tab) bin.packLLIB(name,tab,ext) bin.unpackLLIB(name,exe,todir,over,ext) bin.fileExist(path) NOW io.fileExists(path) bin.closeto(a,b,v) bin.textToBinary(txt) bin.decodeBits(bindata)
• bin.trimNul(s) -- removes the nul character from the end of a string bin.getIndexSize(tab)
• bits.numToBytes(n,fit,func) -- converts a number into a string, helper function for bin.getnumber(num,len,fmt,func), allows for more control binobj:clone() binobj:compare(other binobj,diff)
• binobj:sub(a,b) -- works like string.sub, but for binobjs
• binobj:tonumber(a,b) binobj:getbyte(n) binobj:tobits(i) binobj:getHEX(a,b) binobj:scan(s,n,f) binobj:streamData(a,b) binobj:streamread(a,b)
• binobj:canStreamWrite() -- returns true if a a binobj can be streamed written to
• bitobj:conv(n)
• bitobj:tobytes()
• bitobj:tonumber()
• bitobj:isover()
• binobj:getHash(n) -- returns a fast, but insecure hash blockReader:getBlock(name) binobj:setEndOfFile(n) binobj:reverse()
• binobj:flipbits() -- filps the bits in the binobj binobj:segment(a,b) binobj:insert(a,i) binobj:parseN(n) binobj:getlength() -- now is getSize() binobj:shift(n) binobj:delete(a,b)
• binobj:encrypt(seed) -- encrypts a file
• binobj:decrypt(seed) -- decrypts a file binobj:shuffle() binobj:mutate(a,i) binobj:merge(o) -- binobj:tackE(data) does this so there is no need for merge binobj:parseA(n,a,t) binobj:getHEX(a,b) binobj:cryptM()
• binobj:addBlock(d,fit,fmt) -- adds a block to the bin obj
• binobj:getBlock(t,n) -- gets the block from a binobj
• binobj:setSeek(n) -- starts at 1 not 0 binobj:morph(a,b,d) binobj:fill(n,d) binobj:fillrandom(n) binobj:shiftbits(n) binobj:shiftbit(n,i) binobj:streamwrite(d,n) binobj:open()
• binobj:close() -- closes a streamed file binobj:wipe() binobj:tackB(d)
• binobj:tackE(d,fit,updateseek) -- adds data onto the end of the file binobj:parse(n,f) binobj:flipbit(i) binobj:gsub() blockWriter:addNamedBlock(name,value) bitobj:add(i) bitobj:sub(i) bitobj:multi(i) bitobj:div(i)
• bitobj:flipbits() -- flips the bits of a bitobj
• bitobj:getBin() -- returns the binobj of the bit data
